This package contains type benchmarks tests using attest.

These were initially developed together with David Blass.

• Make sure the overall monorepo has dependency installed (pnpm install in root) and is build (pnpm -r dev or pnpm build in root).
• Run pnpm test to run the test suite
• Run pnpm test:update to update snapshot recordings
• Run pnpm test <filter> to run only files including in their filename
• Run pnpm test:update <filter> to only update snapshots of files including in their filename

• Each folder in this directory contains a different schema.
• Each schema can be tested with multiple *.bench.ts files.
• Each *.bench.ts file can contain multiple attest benchmarks and a dedicated baseline.
• The generated prisma client for each schema can be found in the generated subfolder after a test run.

This project includes several benchmark suites comparing type-checking performance:

• prisma.query.bench.ts - Prisma ORM queries using generated client types
• drizzle.query.bench.ts - Drizzle ORM SQL-like query builder with manual joins
• drizzle.relational.bench.ts - Drizzle ORM Relational Query Builder (RQB) using db.query.* API with with clauses

• prisma.schema.bench.ts - Prisma generated types evaluation
• drizzle.schema.bench.ts - Drizzle schema types evaluation
